- Introduction Recent data suggest that margins >= 2 mm after breast-conserving surgery may improve local control in invasive breast cancer (BC). By allowing large resection volumes, oncoplastic breast-conserving surgery (OBCII; Clough level II/Tubingen 5-6) may achieve better local control than conventional breast conserving surgery (BCS; Tubingen 1-2) or oncoplastic breast conservation with low resection volumes (OBCI; Clough level I/Tubingen 3-4). Methods Data from consecutive high-risk BC patients treated in 15 centers from the Oncoplastic Breast Consortium (OPBC) network, between January 2010 and December 2013, were retrospectively reviewed. Results A total of 3,177 women were included, 30% of whom were treated with OBC (OBCI n = 663; OBCII n = 297). The BCS/OBCI group had significantly smaller tumors and smaller resection margins compared with OBCII (pT1: 50% vs. 37%, p = 0.002; proportion with margin <1 mm: 17% vs. 6%, p < 0.001). There were significantly more re-excisions due to R1 ("ink on tumor") in the BCS/OBCI compared with the OBCII group (11% vs. 7%, p = 0.049). Univariate and multivariable regression analysis adjusted for tumor biology, tumor size, radiotherapy, and systemic treatment demonstrated no differences in local, regional, or distant recurrence-free or overall survival between the two groups. Conclusions Large resection volumes in oncoplastic surgery increases the distance from cancer cells to the margin of the specimen and reduces reexcision rates significantly. With OBCII larger tumors are resected with similar local, regional and distant recurrence-free as well as overall survival rates as BCS/OBCI.

Democracy and its Critics
- 2017

Bok (refereegranskat)abstract
- There are few better examples of analysis - the critical thinking skill of understanding how an argument is built - than Robert Dahl's Democracy and its Critics. In this work, the American political theorist closely analyzes the democratic political system and then evaluates whether the arguments that are in favor of it are, in fact, rigorous. Dahl sets out to describe democracy's merits and problems, asking if it really is the worthwhile political system we believe it to be. Knowing that the idea of democracy is now almost universally popular, his detailed analysis leads him to look at a number of regimes that claim to be democratic but do not, in truth, practice democracy. But Dahl is not only interested in uncovering uncomfortable truths. He goes further and creates a set of standards by which we can all decide whether a country really is democratic. Dahl's analysis of the evidence leads him to conclude that the following criteria must be met for a regime to be considered truly democratic: elected officials control policy-making; there are free and fair elections of officials; everyone must have a right to vote; everyone has the right to run for office; there is freedom of speech; alternative information is available; and people can form free, independent political groups.

- Chronic obstructive pulmonary disease (COPD) is the leading cause of respiratory mortality worldwide. Genetic risk loci provide new insights into disease pathogenesis. We performed a genome-wide association study in 35,735 cases and 222,076 controls from the UK Biobank and additional studies from the International COPD Genetics Consortium. We identified 82 loci associated with P < 5 x 10-8; 47 of these were previously described in association with either COPD or population-based measures of lung function. Of the remaining 35 new loci, 13 were associated with lung function in 79,055 individuals from the SpiroMeta consortium. Using gene expression and regulation data, we identified functional enrichment of COPD risk loci in lung tissue, smooth muscle, and several lung cell types. We found 14 COPD loci shared with either asthma or pulmonary fibrosis. COPD genetic risk loci clustered into groups based on associations with quantitative imaging features and comorbidities. Our analyses provide further support for the genetic susceptibility and heterogeneity of COPD.
